FIELD OF THE INVENTION

[0001] The present invention relates to novel substituted quinazolines which are useful for preparing medicinal products for treating complaints involving a therapy with a matrix metalloprotease-13 (MMP-13) inhibitor. These medicinal products are useful in particular for treating certain inflammatory conditions such as rheumatoid arthritis or osteoarthritis, as well as certain proliferative conditions such as cancers.

TECHNOLOGICAL BACKGROUND OF THE INVENTION

[0002] Matrix metalloproteases (MMPs) are enzymes which are involved in the renewal of extracellular matrix tissue, such as cartilage, tendons and joints. MMPs bring about the destruction of the extracellular matrix tissue, which is compensated for, in a non-pathological physiological state, by its simultaneous regeneration.

[0003] Under normal physiological conditions, the activity of these extremely aggressive peptidases is controlled by specialized proteins which inhibit MMPs, such as the tissue inhibitors of metalloprotease (TIMPs).

[0004] Local equilibrium of the activities of MMPs and of TIMPs is critical for the renewal of the extracellular matrix. Modifications of this equilibrium which result in an excess of active MMPs, relative to their inhibitor, induce a pathological destruction of cartilage, which is observed in particular in rheumatoid arthritis and in osteoarthritis.

[0005] In pathological situations, an irreversible degradation of articular cartilage takes place, as is the case in rheumatic diseases such as rheumatoid arthritis or osteoarthritis. In these pathologies, the cartilage degradation process predominates, leading to a destruction of the tissue and resulting in a loss of function.

[0006] At least twenty different matrix metalloproteases have been identified to date and are subdivided into four groups, the collagenases, the gelatinases, the stromelysins and the membrane-type MMPs (MT-MMPs), respectively.

[0007] Matrix metalloprotease-13 (MMP-13) is a collagenase-type MMP which constitutes the predominant collagenase observed during osteoarthritis, in the course of which pathology the chondrocyte directs the destruction of cartilage.

[0008] There is a need in the prior art for novel MMP inhibitors, more particularly for MMP-13 inhibitors, in order to prevent and/or correct the imbalance in the renewal of extracellular matrix tissue, such as arthritis, rheumatoid arthritis, osteoarthritis, osteoporosis, periodontal diseases, inflammatory bowel disease, psoriasis, multiple sclerosis, cardiac insufficiency, atherosclerosis, asthma, chronic obstructive pulmonary diseases (COPD), age-related macular degeneration (ARMD) and cancer.

[0009] MMP-inhibitor compounds are known. Most of these MMP-inhibitors are not selective for a single MMP, such as those described by Montana and Baxter (2000) or by Clark et al. (2000).

[0010] There is also a need in the prior art for novel inhibitors that are active on matrix metalloprotease-13, in order to enrich the therapeutic arsenal that can be used for treating pathologies associated with the destruction of the extracellular matrix and with cancer.

[0347] The invention also relates to the pharmaceutically acceptable salts of the compounds of formula (I). A review of the pharmaceutically acceptable salts will be found in J. Pharm. Sci., 1977, vol. 66:1-19. However, the expression “pharmacologically acceptable salts of a compound of formula (I) with a basic function” means the addition salts of the compounds of formula (I) formed from non-toxic mineral or organic acids such as, for example, hydrobromic acid, hydrochloric acid, sulphuric acid, phosphoric acid, nitric acid, acetic acid, succinic acid, tartaric acid, citric acid, maleic acid, hydroxymaleic acid, benzoic acid, fumaric acid, toluenesulphonic acid, isethionic acid and the like. The various quaternary ammonium salts of the compounds of formula (I) are also included in this category of compounds of the invention. In addition, the expression “pharmacologically acceptable salts of a compound of formula (I) with an acid function” means the usual salts of the compounds of formula (I) formed from non-toxic mineral or organic bases such as, for example, the hydroxides of alkali metals and of alkaline-earth metals (sodium, potassium, magnesium and calcium), amines (dibenzylethylenediamine, trimethylamine, piperidine, pyrrolidine, benzylamine and the like) or quaternary ammonium hydroxides such as tetramethylammonium hydroxide.

[0348] As mentioned above, the compounds of formula (I) of the present invention are matrix metalloprotease inhibitors, and more particularly inhibitors of the enzyme MMP-13. In this respect, their use is recommended in the treatment of diseases or complaints involving a therapy by MMP-13 inhibition. By way of example, the use of the compounds of the present invention may be recommended during the treatment of any pathology in which a destruction of extracellular matrix tissue is involved, and most particularly pathologies such as arthritis, rheumatoid arthritis, osteoarthritis, osteoporosis, periodontal diseases, inflammatory bowel disease, psoriasis, multiple sclerosis, cardiac insufficiency, atherosclerosis, asthma, chronic obstructive pulmonary disease (COPD), age-related macular degeneration (ARMD) and certain cancers.

[0349] Selectivity of the Compounds of Formula (I) for the Enzyme MMP-13

[0350] Most of the matrix metalloprotease inhibitors described in the prior art are non-selective inhibitors, capable of simultaneously inhibiting several matrix metalloproteases. For example, compounds such as CGS-27.023A and AG-3340 (Montana and Baxter (2000)) inhibit both MMP-1, MMP-2, MMP-3, MMP-9 and MMP-13, i.e. these compounds of the prior art inhibit MMPs of both collagenase, gelatinase and stromelysin type.

[0351] It has been shown according to the invention that compounds of general formula (I) are selective inhibitors of MMP-13. “Selective inhibitors of MMP-13” refers to a compound of formula (I) which have an IC₅₀ for MMP-13 at least 5 time lower than the IC₅₀ for a MMP distinct from MMP-13, and preferably at least 10 times, 15 times, 20 times, 30 times, 40 times, 50 times, 100 times or 1000 times lower than the IC₅₀ value for a MMP distinct from MMP-13.

[0352] A MMP distinct from MMP-13 refers preferably to a matrix metalloprotease selected from MMP-1, MMP-2, MMP-3, MMP-7, MMP-9, MMP-12 and MMP-14.

[0353] In particular, it has been shown according to the invention that the compounds of general formula (I), and more particularly the family of compounds given as examples in the present description, have an IC₅₀ value for the enzyme MMP-13 which is often 1 000 times lower than the value of their IC₅₀ for other matrix metalloproteases, in particular MMP-1, MMP-2, MMP-3, MMP-7, MMP-9, MMP-12 and MMP-14.

[0354] The result of this is that the compounds of general formula (I) according to the invention are particularly useful in the treatment of complaints mainly associated with a physiological imbalance between the MMP-13 enzymes and their natural tissue inhibitors.

[0355] Pharmaceutical Formulation of the Compounds of the Invention

[0356] A subject of the present invention is also a pharmaceutical composition comprising a compound of general formula (I) as defined above and a pharmaceutically acceptable excipient.

[0357] The invention also relates to the use of a compound of general formula (I) as defined above for the preparation of a medicinal product intended for treating a disease or complaint involving therapy by inhibition of matrix metalloprotease, and more particularly a disease or complaint involving therapy by inhibition of type-13 matrix metalloprotease (MMP-13) such as arthritis, rheumatoid arthritis, osteoarthritis, osteoporosis, periodontal diseases, inflammatory bowel disease, psoriasis, multiple sclerosis, cardiac insufficiency, atherosclerosis, asthma, chronic obstructive pulmonary disease (COPD), age-related macular degeneration (ARMD) and cancers.

[0358] The invention also relates to a method for treating a pathology associated with an imbalance in the activity of MMPs, and more specifically of MMP-13, the said method comprising a step during which a pharmaceutically effective amount of an MMP-inhibitor compound according to the invention, or a pharmaceutical composition containing this compound, is administered to a patient requiring such a treatment.

[0359] Among the various pathologies associated with an imbalance in MMP activity, an MMP-13-inhibitor compound of general formula (I) according to the invention is particularly useful for treating all pathologies brought about by a degradation of extracellular matrix tissue, and more particularly for treating rheumatoid arthritis, osteoarthritis, osteoporosis, periodontal diseases, inflammatory bowel disease, psoriasis, multiple sclerosis, cardiac insufficiency, atherosclerosis, asthma, chronic obstructive pulmonary disease (COPD), age-related macular degeneration (ARMD) and cancer. In an entirely preferred manner, a compound of general formula (I) as defined according to the invention will be used, preferably to treat arthritis, osteoarthritis and rheumatoid arthritis.

[0360] The compounds of the invention are administered in the form of compositions that are suitable for the nature and gravity of the complaint to be treated. The daily dosage in man is usually between 2 mg and 1 g of product which may be absorbed in one or more dosage intakes. The compositions are prepared by methods that are common to those skilled in the art and generally comprise 0.5% to 60% by weight of active principle (compound of formula I) and 40% to 99.5% by weight of pharmaceutically acceptable vehicle.

[0361] The compositions of the present invention are thus prepared in forms that are compatible with the desired route of administration. By way of example, the following pharmaceutical forms may be envisaged, although the list given below is not limiting:

[0362] 1) Forms for Oral Administration

[0363] Drinkable solutions, suspensions, sachets of powder for drinkable solution, sachets of powder for drinkable suspension, gastro-resistant gel capsules, sustained-release forms, emulsions, HPMR capsules or gel capsules, lyophilizates to be melted under the tongue.

[0364] 2) Forms for Parenteral Administration

[0365] Intravenous Route

[0366] Aqueous solutions, water/cosolvent solutions, solutions using one or more solubilizing agents, colloidal suspensions, emulsions, nanoparticulate suspensions which can be used for the injection of sustained-release forms, dispersed forms and liposomes.

[0367] Subcutaneous/Intramuscular Route

[0368] In addition to the forms which can be used intravenously and which can also be used for the subcutaneous and intramuscular routes, other types of forms such as suspensions, dispersed forms, sustained-release gels and sustained-release implants may also be used.

[0369] 3) Forms for Topical Administration

[0370] Among the most common topical forms that are distinguished are creams, gels (aqueous phases gelled with polymers), patches, which are dressings to be stuck directly onto the skin and which can be used to treat dermatosis without percutaneous penetration of the active substance, sprays, emulsions and solutions.

[0371] 4) Forms for Pulmonary Administration

[0372] Forms such as solutions for aerosols, powders for inhalers and other suitable forms are distinguished in this category.

[0373] 5) Forms for Nasal Administration

[0374] This especially relates herein to solutions for drops.

[0375] 6) Forms for Rectal Administration

[0376] Suppositories and gels will be selected, inter alia.

[0377] It is also possible to envisage using forms allowing the administration of ophthalmic solutions or allowing the vaginal administration of the active principle.

[0378] Another important category of pharmaceutical form which may be used in the context of the present invention relates to forms for improving the solubility of the active principle. By way of example, it may be envisaged to use aqueous solutions of cyclodextrin, and more particularly forms comprising hydroxypropyl-β-cyclodextrin. A detailed review of this type of pharmaceutical form is presented in the article published under the reference Journal of Pharmaceutical Sciences, 85 (11), 1142-1169 (1996), and incorporated into the present patent application by reference.

[0379] The various pharmaceutical forms recommended above are described in detail in the book “Pharmacie galenique” by A. Lehir (published by Masson, 1992 (6th edition)), which is incorporated into the present patent application by reference.

[2296] Evaluation of the in vitro Activity of the Compounds of Formula (I) According to the Invention

[2297] The ability of the compounds of formula (I) of the invention to inhibit matrix metalloprotease 13 was evaluated by measuring their IC₅₀ value (concentration required to inhibit 50% of the enzymatic activity) according to the protocol described below. MMP13CD Thiopeptolide Assay: Proteolysis of the thiopeptolide substrate Ac-Pro-Leu-Gly-thioester-Leu-Leu-Gly-OEt is used as the primary screen to determine IC₅₀ values for MMP13 inhibitors. A 100 μl reaction contains 50 mM HEPES, 10 mM CaCl₂, pH 7.0 (RT), 1 mM 5,5′-dithiobis(2-nitrobenzoic acid) (DTNB), 100 μM substrate, inhibitor in 2.0% DMSO and 2.5 nM human collagenase-3 catalytic domain enzyme. Inhibitors are screened from 100 μM to 0.5 nM. The change in absorbance at 405 nm is monitored on a microplate reader at room temperature continuously for 10-15 minutes. Percentage of control velocity in inhibited treatments is plotted against inhibitor concentration to calculate IC₅₀ values. TABLE 1 Example IC₅₀ (μM)  5 0.193  6 0.183  7 0.021  8 1.87  9 0.366 10 0.049 11 0.167 12 1.32 13 0.005 14 0.057 15 2.25 16 0.042 17 0.012 18 0.051  19d 0.7 20 0.015 21 0.009  22b 0.01 24 0.051 25 0.3 26 0.096 27 0.029 28 0.009 29 0.028 30 0.009 31 1.7 32 0.017 33 0.003 34 0.026 35 0.157 36 0.6 37 0.75  38b 0.004 39 0.001 40 0.028 41 0.029 42 0.031 43 0.011 44 0.004 45 0.007 46 0.0025 47 1.21 48 0.016 49 0.007 50 0.096 51 0.062 52 0.014

[2298] Examination of the results of Table 1 shows that the products of the invention tested in the assay effectively inhibit matrix metalloprotease 13.

[2299] The protocol described above was also used to measure the activity of the compounds of the invention against MMP1, MMP2, MMP3, MMP7, MMP9, MMP12 and MMP14. The IC₅₀ values obtained on these MMPs were often greater than 100 μM. These results the compounds of the invention are selective MMP13 inhibitors.
